OUR MEASUREMENT

During the analysis the meter will display the ongoing calculation.

At the end of the analysis the meter will display the computed

 

SOUR value, the duration of the 

measurement, and the pressure and temperature values. Press 

Log

 to record a record of this analysis.

To analyze another sample, clean and dry off probe. Place probe into the next prepared sample.
Press 

Start

.

SOUR Error messages

 will be displayed anytime a measurement exceeds the limits that were 

configured. These will have to be reconfigured and the analysis restarted. Examples follow.
If the DO reading is less than the minimum end DO value set during SOUR configuration, a warning 
icon will be displayed and a beep will be heard every two seconds. Press 

Stop

 to stop the test and 

the beeper.
In case that the SOUR value is corrected to 20 °C (68 °F) and the measured temperature isn’t in the 
range 10 to 30 °C the temperature value will blink to alert that the temperature correction isn’t valid.

 

Press 

LOG

 to save a complete set of data regarding the

 

SOUR test.

Press 

Start

 to begin a new

 

SOUR test.

Notes:

 If the DO reading is less than the minimum end DO value set during SOUR configuration, 

a warning message will be displayed. Press any key to clear the message from the screen, or 

press HELP to view detailed information about the warning. If the DO value is greater than the 

DO value from the beginning of the test an error message will be displayed.
